At the same blow ratios , the double - layer porous plate exhibits higher cooling effectiveness than single - layer , but the difference of cooling effectiveness between the triple - layer plate and the double - layer plate is not significant 在相同吹風(fēng)比下,雙層層板要比單層層板冷卻有效性高,而三層層板與雙層層板之間的差別不大。
A triple - layer radar absorbing coatings composed of dielectric and magnetic materials were prepared according to resistance matching principal , which is then further coated with an infrared and visible light camouflage coatings 摘要依據(jù)阻抗匹配原理制備了一種3層雷達(dá)吸波涂層,并在吸波涂層表面噴涂一定厚度的可見光、紅外偽裝涂料,比較了噴涂偽裝涂料前后涂層吸波性能的變化。
In a word , the two type of voa both have valuable applicability and potential market . the author have done numerous processing to work out new processing such as polymer coating and cure and triple - layer - metal film vaporing . other new processing , polymer ultra - violet ( uv ) cure and inductively - coupled plasma ( icp ) etching were studied 作者經(jīng)過反復(fù)的工藝實(shí)驗,確定了聚合物波導(dǎo)涂膜和固化、三層金屬電極蒸發(fā)和腐蝕等新工藝的參數(shù),并得到了聚合物紫外固化、等離子體刻蝕等新工藝的初步數(shù)據(jù)。
